LTC1403ACMSE#PBF

The LTC1403ACMSE#PBF is a serial 12-bit sampling Analog-to-digital Converter (ADC) with shutdown. The devices draw only 4.7mA from a single 3V supply. A sleep shutdown feature lowers power consumption to 10µW. The combination of speed, low power and tiny package makes the LTC1403A suitable for high speed, portable applications. The 80dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source. The device converts 0 to 2.5V unipolar inputs differentially. The absolute voltage swing for +AIN and -AIN extends from ground to the supply voltage. The serial interface sends out the conversion results during the 16 clock cycles following CONV↑ for compatibility with standard serial interfaces. If two additional clock cycles for acquisition time are allowed after the data stream in between conversions, the full sampling rate of 2.8Msps can be achieved with a 50.4MHz clock.
